Attorneys To all whom it may wneern:

Be itknown that I, Batman 0. Dana, a citizen of the United States, residin at Coalinga, in the county of Fresno and tate of California have invented a new and useful Packer or Oil or Artesian \Vells, of which the following is a s ecilication.

The device constituting t to subject-matter of this application is a )acking structure adapted to be employed or closing a leak in the buildin of a well.

The invention aims to provide novel means for sustaining the packing element, and to provide novel means for actuating 15 the packing element radially to engage .wit 1 4 the tubing.

A furt ier object of the invention is to provide a device of this type in which the constituent members are assembled in a novel manner to lprovide for the mounting of the packing e ement in place upon the carr ing rtion oi the structure.

ith t e fore mg and other-objectsun view, which wil appear'as the descript1on proceeds, the invention resides in the comination and arrangement of parts and m the details of cons ruction hereinafter described and claimed, it being understood that chan es in the precise embodiment of invention erein disclosed can be made within the scope of what is claimed without departin from the spirit of the invention.

In t e drawin Figure 1 shows the invention'in side e ovation; and 2 is a longitudinal section, the parts in ig. 2 being shifted slightly from the positions shown in Fig.4. a g

In earryin out the invention there is provided a tube ar sleeve 1, internally threaded V at its up r end as denoted by the numeral 2 and in ernallv threaded at its lower end as denoted by the'numeral 8 'the intermediate portion 4 of the liorefof the sleeve 1 being enlargpd in diameter slightly, and being smoot as indicated at The invention further includes a tubular ""end as denotedizby thenumeral 6, for engpgementjwith the threads 2 of the sleeve 1. titsu per end, the lungler 5 is externally thread as indica atthe outer-dace ot the 'plunger ing smooth-"between the '1threadsufi i andijsjt g f e; i, The; invention! rtherjincludes a com 'ined'eonphn and abutment 8, internally. hre ed-vss s wn atBttor, engagement STATES.

with the threads 7 of the plunger 5, al- 7 thou h a union between the member 8 and the p unger 5 may be effected in any other desired manner.

A wedge ring D incloses the plunger the upper portion of the periphery of the ring 9 bein of a common diameter with the exterior ace of the member 8, as shown at 10. The wedge face of the ring 9 is indicated at 11, and upon the plunger 5 there is formed it tapered s oulder 12, constituting a continuation of the wed face 11 of the ring 9. The upper end the ring 9 abuts against the member 8.

Surrounding the plunger is a tubular, resilient aching-denoted by the numeral 14. The ower end of the packing 14 abuts against the upper end of the sleeve 1, the

'packin 14 lying between the sleeve 1 and the we a ring 9.

As wi be understood, an auxiliary tubing is threaded into the portion 8" of the couling member 8, an extension of the auxiliary tubing being assembled with the lower threads 3 of the sleeve 1, when desired.

,The parts being positioned as shown in Fig: 1, the auxiliar tubin to ether with the structure herein fore escri ed, is lowered into lace within the old tubing of the well, unti the leak is reached. Thereupon the auxiliary tubing and the couplin 8 are rotated, the lower end of the con ling 8 enga ing the wed e 0 and forcing t same into t e upper en 01 the packing 14, it being noted that the packing 1 is retained at its lower end b engagement with the sleeve 1. .During is initial advancement of the wedge rin 0 in the paekin 14, the packin 14 will be eilected outwar y by the taperec shoulder of the plunger 5 the operation and construction bein such that the packing It will be prevente from catching upon the thinned edge of the wedge ring 9. Continned -.rotation of the cou ling member 8 and'of the plunger 5 wil cause a disengagement between the upper threads 2 of the sleeve 1 and the lower threads 6 of the plunger 5, whereupon the longer 5, bein actuated gravitattonallv y tie entire weight; of the auxiliary tu ing, will more downwardly with abrupt, dropping movcmeat, the wedge 9 being advanced into the packing 14, to expand the packing radiy. the fore mgoperation, a tight joint will be f orme between the plunger 5, the

packing 1 1," well, it being impossi 1e, therefore, for water to flow downwardly through the leak "in the original tubing, and into the well.

It is to be noted that the rin 9 is detachable from'the plunger 5,- an therefore the packing 14 maybe placed about the plunger 5, m abutment with the upper end of the sleeve 1, the ring 9 being placed subsequently about the plunger 5, the coupling 8 being ultimately mounted upon the plunger 5, tohold the ring 9 in place.

Ilavin thus described the invention, what is c aimed is 1. In a deviceof the class described, a sleeve; a plun r detachably threaded into the sleeve for a rupt dropping movement; a combined couplin and a utment removably carried by the p anger; a wedge rin surrounding the plunger and engageable y the abutment; and. a packing surrounding the plunger and abut-ting against the sleeve, the ring being removabe to provide for the mounting of the packing, the ring being initially advanced intothe packing upon rotatory mm'ement-between the sleeve and the plan r andbeing :tinally advanced theremto y the droppin action of the plun r.
